Emitting smoke off a curving mesh
Ok, so I've learned a lot since then, and after a long while of putting it off because I didn't like having to redo stuff, I managed to fix it myself. This is what I've learned:

First off, size does matter. Having a kilometer large room doesn't help (Source models are huge so always scale down).

Secondly, I figured out that the smoke is created on a grid-based system, which is determined by the Divisions. Though by amplifying that number tends to cause the program (or whole computer) to be unresponsive.

Because of these things, it felt best to make several smaller Domains that surrounded the tubes rather than the whole room.

And finally, I removed a few elements from the smoke material, and that was the color Attribute and the additional Add shader.

The results finally came together nicely, even with a few redos...
